The latest prevention and control of lotus diseases and insect pests

The lotus fog itself has a special smell, which is easy to attract some insects, thus causing diseases. Secondly, the pericarp of lotus flower is very thin, its defense ability against some diseases is poor, and it is very easy to be eroded by diseases. So what are the diseases and insect pests of lotus flower? Let's learn more about it.

1. Anthrax

Anthracnose is encountered by many fruit trees, and lotus fog is no exception. When the disease occurs and does great harm to the fruit, it generally starts from the top of the fruit and spreads around. First, there are some brown spots, along with the disease and the brown spots on the top of the fruit go deep into the fruit, causing the fruit to rot. When the leaves appear, the brown spots also spread, and the leaves slowly dry up. You can spray with a 600-fold solution of 80% mancozeb wettable powder, or a 600-fold spray of 50% methyl topiramate wettable powder, and follow the instructions.

2. Fruit rot

When the disease occurs, there will be some water-like spots on the lotus fog, which can be divided into brown and purple. As time goes by, the whole fruit looks like it has withered, and the whole fruit has changed color. Amisida 1500 times liquid, Baitai 1500 times liquid spray and so on can be regarded as agents for lotus fruit rot, but try not to use them 2 weeks before harvest, and use the recommended dosage, especially in terms of concentration.

3. Drosophila orientalis

Oriental fruit flies are mainly attracted by the fragrance of lotus mist, which basically only harms the fruit. Generally, the mother lays eggs on the lotus mist, which is used as a hatching base, and the larvae begin to absorb the nutrition of lotus mist after birth. Oriental fruit fly larvae will climb into the lotus fog to get more nutrients, so when oriental fruit fly pests appear, many lotus flowers will have wormholes and rot. This can be treated with drugs such as 25% marathon wettable powder, or you can choose to place insect traps around to reduce the risk of the disease.

4. Thrips

Insects such as thrips do little harm to the fruit, but pose a greater threat to the leaves and flowers of the lotus tree, resulting in the fruit from ripening normally. The harm to leaves is to absorb nutrients, causing leaves to keep falling, and for flowers to destroy their internal structure, resulting in a variety of deformities or defects in the fruit. Things like beta-cyhalothrin and deltamethrin can be considered, but it's best to use them as directed by your doctor, because it's harmful.

5. Green leafhopper

Green leafhopper is a disease encountered by all kinds of fruit trees, and their biggest threat is to hinder the growth of new branches of fruit trees. The green leafhopper is very particular about its habitat, only pursuing fresh branches and leaves, so the inspection of the green leafhopper should pay more attention to these places. After the occurrence of this pest, there is something wrong with the new branches and leaves, which often bend or curl up. You can open these leaves to see if there is anything abnormal. This can be considered under 50% parathion 2000 times solution, the effect is OK.
